Hello everyone, I am the ruffian, a serious ruffian who engages in technology. Today Pi Ziheng is introducing domestic RISC-V core MCU manufacturers .
Although the RISC-V wave has been blowing for several years, 2019 is the first year for it to truly enter the mainstream market. Recently, a large number of domestic chip companies have risen, and many of them want to do something in the new RISC-V track. After all, ARM The kernel is already in the Red Sea, and RISC-V is still in the Blue Sea. Today, Pi Ziheng will take stock of the manufacturers who have released RISC-V MCU products (not necessarily in mass production):
1. Core interconnection CLE
Xuanji CLE series is a general-purpose embedded MCU processor launched by Core Interconnect based on a 32-bit RISC-V core (Quark Q series). It is mainly suitable for white goods, industrial control, Internet of Things and other requirements for stability, power consumption and computing capabilities. Higher application areas.
Xuanji CLE series has ultra-high bandwidth and two-stage pipeline RISC-V Harvard architecture. The computing performance can reach 45 DMIPS at the maximum operating frequency of 32MHz, which meets the ultra-low power design. The full-featured standby power consumption is 7.5μA. The consumption is 51μA/MHz, which is suitable for 1.6V-5.5V ultra-wide working voltage. Xuanji has a large-capacity eFlash, code cache and data cache, rich communication peripheral interfaces, and a built-in high-precision OSC oscillator. It is worth mentioning that Xuanji CLE series RAM reaches 48KB, which can fully meet the control needs of different home appliances and application scenarios.
